Application filed February 15, 1909. Serial No. 477,957.

. printing envelops, the same being of the tively simple and inexpensive parts to prove l rotary type and having novel means for coni trolling the inking mechanism and the feeding mechanism upon failure of the said feeding mechanism to properly operate.

An object of this invention is to provide novel means for actuating a controller for the inking mechanism and simultaneously therewith for operating guards which limit the movement of certain parts which, owing to said limitation, causes the mechanism and particularly the feeding mechanism to move in order to guard against the operation of the printing mechanism if the feeding action is not normal.

To the end stated, I provide a series of links and 'levers and two guards or shutters, one of which operates in conjunction with the envelop/carrier and the other of which i operates inconjunction with means for con .j trolling the inking mechanism whereby the objects indicated are attained by comparastrong and durable well as efficient and' satisfactory. in use.-

With the foregoing and .other objects in 1 view, the invention consists in the details of construction and inthe arrangement and,` combinationgof parts .to be hereinafter more l fuliy set forth and claimed.

in describing the invention in detail,-ref erence` will be had to the accompanying drawings forming part of this specification wherein like characters denote correspondl ing parts in theseveral views, in which- Figure 1, illustrates a fragment of a frame i of a printing press with parts of the operating mechanism in elevation and other parts i shown in dotted lines back of the frame; Fig. 2, illustrates a' fragment of a printing ,l frame taken from the side opposite to that l shown in Fig. 1', Aparts of the mechanism i being shown in elevation and other parts in l dotted lines; Fig. 3, illustrates an end view/ififrom alinement with the aperture 1l, in the of a feed roll withy nide rolls in assembled relation therewith; *ign 4, illustrates a view l Specification of Lettersatent.

similar to Fig. 3, except that the feed roll is shown .in section as is also one of the guide rolls, the guard mechanism being shown in osition from that in which it is illustrated in Fig. 8; Fig. 5, illustrates a view in elevation of a feed roll and the i guard operating mechanism operating in conjunction therewith; Fig. 6, illustrates a plan view of a fragment of the mechanism for controlling the guard; and F ig. 7, illustrates a top plan view of a lever anda cam acting inconjunction with the lever.

In these drawings 1, denotes a frame, 2, the envelops to be printed, and 3, the tinislied product.,

The envelops are fed from one side of the `printing mechanism carried by the frame to the other side of said printingmechanism and in order to accomplish the result, the frame is provided with a feed roll 4f, having aperipheral groove 5,' the said feed roll being mounted on a shaft G. and in conjunction with the feed roll a series of guide rolls 7 operate. One of the guide rolls '7, is provided with a peripheral gi'oove S, which' alines with a peripheral groove 5, of the feed roll 4:. A guard or finger 9, is mov- 4 able with -relation to the feed uroll 4Q, and the guide roll containing the peripheral groove, the said guard being oscillated to move into contact with the wall of the groove of thev feed roll or the wall of the groove of the guide roll according to the relation of other parts of the mechanism to be hereinafter i described, and the action of the guard when it is in contact with the feed roll is to cause theyseparation of the rolls of the printing mechanism as will be presently explained.

The outer end of the guard, that is to say, the end'of the guard remoto from the feed roll is connected to a thrustL rod 10, in order that the said guard may be moved with re lation to an aperture 11, formed in a bracket 12. The/thrust rod is slidablethrough a loop 13, on the outer end of the guard and said thrust rod is provided with a collar 11i, which is adjustably secured to it by means of a screw 15, and lwhen the thrust rod moves in the loop 13, until the collar i4,

abuts the loop, further movemem of the thrust rod will communicate motion to the guard and oscillate it on its -pivct it, in order tosearry the outer end of said rod bracket, so that the unguarding of the aperture permits the admission of a har te ine aperture. The pivotY guard projects from the post 16, which is i 'tegral with or lever is operated, -mot1on 1s communloated to attached to the 'bracket A12 As shown `in the thru t rod 10, to the guard 22, and to Fig. 4 When the guard is in the position the 'rod 37,and when theaperture 11, is unthere illustrated, .the aperture 11, is un-` guardedto permit the rod 37, toenter, the 7o guarded Whereas theinnerl end of said said rod will travel a suffclent'distance to guard is out of the groove 5, in the feed oscillate the lever 18, and thus communicate roll and is .lying in t e groove 8, of a guide motion torthe ard 22, in or er to throu7 roll, Whereas i-n Figiv'3, the inner end of the said guard in line with the aperture 26, to guar is shown as I-'ying 1n the Agrooves of `prevent' the entrance therem of a refrul'atinfr 75 the feed roll 4, with the outer end of said evice v(to presently explained) guard obstructing the aperture 1l. The1 shaft 6,containing the feed roll has -The .thrustrod 10, projects from an ii-frm' mounted on its end a compound -cam com- 17, which arm 4is referably integral-with posed of two.`sitle` cams 41 and 42, an eccenthe lever 18, pivota l mounted o n the frame tric 43,andfa round wheel 44. 'A lever 45, 80 One end of the ever 18, has a link19, asfan angular portion 46, connected to a extending to. the side and projecting beyond shaft 47, and the outer end of said lever has the frame, the outer end of said lever hava'` plunger 48, which is designed to`reciproing a pin 20, operating in a slot 2l, of a cate in the aperture 26, of the lu on the arm pivotally mounted guard 22. A bracket .23, 23, the movement of the said p u'nger being 85 has an arm 24, to which the guard is pivcontrolled by the guard 22, heretofore def oted and said bracket is also provided Withl scribed. The lever 45,;is also provided with a lug '25.
